The timing of it all is working out very well. Isaka gives him a nod, looks back to the barista working on preparing drinks, and ah, they've set them down to be taken. So he takes both of them, in paper to-go cups with little lids snapped on, and hands one to Tachibana. "You take yours black, yes?" And he'll find that's just what it is.

With drinks arranged, Isaka gives a little 'come along with me' tilt of his head and makes for a table in the far corner. Some moderate privacy for their meeting.
